I recently began a playthrough of BG2:EE with Artemius' (quite excellent) troubadour kit mod installed, and I encountered some seemingly buggy behavior in which NPCs would intermittently lose the effects of bard songs on them when they were moving. I initially thought that this might be a bug related to the mod kit, but I tested out a vanilla bard on an unmodded download of BG2, and I encountered the same problem.
I did some research on this issue, and I read that this was reportedly an issue back in the vanilla BGs, although I can't recall encountering it myself (although admittedly, I didn't play as a bard much back then). I also read that this bug may have been re-introduced to the BG:EEs by one of the more recent patches.
I should note that I'm NOT playing with the most recent update of BG2:EE installed, as I didn't like some of the changes that were made around the time of SoD's release.
So my question is, is this a known bug that has since been fixed by one of the more recent updates to BG2:EE? And by any chance, is there a hotfix out there that I could simply download and place in my override folder so that I could continue using my current version of the game?
